For instance right now I take fierce preworkout. Yes I've tried just about everything, no xplode, wtf pump'd, ragnarok, vasoxplode, superpump 250, you name it. I just happen to prefer fierce over them all.

So if I were to mix up some xtend and sip on it during my workout, does that mean I should nix the fierce pre workout and just go with the xtend?

I could mix them I guess, but orange fierce mixed with lemon xtend......maybe not such a great idea

I sure do take a pre workout supp. I am taking NO Xplode, and when I get the chance and get some samples, I will take something like Smash, Supercharge, Steel Edge, it all depends. They all do the same thing (relatively). I take my pre workout supp with my vitamin, and that's it. I don't like to mix anything else with it in fear that the amino acids could interfere with NO production. Plus, drinking BCAA's during my workout keeps me more anabolic. I take bcaa's an hour before my workout with protein, during my workout, then immediately post. The only way I'd say I wouldn't take a pre workout supp is if I was taking something like amino shooter with caffeine, but still I'd want something to give me a pump.
